Subject: [PATCH 05/19] powerpc/chrp/setup: Add attribute unused and make some functions static

Add gcc attribute unused to silence a warning.

These functions can all be static, make it so. Fix warnings treated as
errors with W=1:

  arch/powerpc/platforms/chrp/setup.c:97:6: error: no previous prototype for ‘chrp_show_cpuinfo’ [-Werror=missing-prototypes]
  arch/powerpc/platforms/chrp/setup.c:302:13: error: no previous prototype for ‘chrp_setup_arch’ [-Werror=missing-prototypes]
  arch/powerpc/platforms/chrp/setup.c:385:16: error: variable ‘idu_size’ set but not used [-Werror=unused-but-set-variable]
  arch/powerpc/platforms/chrp/setup.c:526:13: error: no previous prototype for ‘chrp_init_IRQ’ [-Werror=missing-prototypes]
  arch/powerpc/platforms/chrp/setup.c:559:1: error: no previous prototype for ‘chrp_init2’ [-Werror=missing-prototypes]
